The Space Show Presents Marc Berte & Paul Jaffe of the Overview Energy Co. Friday, 2-6-26

Quick Summary

The Space Show hosted a discussion about space solar power with Marc Berte, CEO of Overview Energy, and Paul Jaffe, Vice President of Systems Engineering at Overview. The conversation focused on Overview’s innovative approach to space solar power, which involves beaming near-infrared light from geosynchronous orbit to existing large-scale solar projects on Earth. Marc explained how their system could potentially provide utility-scale power at a lower cost than other space solar concepts, with a target of delivering the first megawatt to the grid by 2030 and a gigawatt by the mid-2030s. The discussion covered technical details such as efficiency, launch costs, and regulatory considerations, with Marc emphasizing that their approach could complement rather than replace existing energy sources. The conversation also touched on potential challenges like debris impact and maintenance in space, with Marc noting that the distributed nature of their satellite constellation would make the system more resilient.

Detailed Summary:

The Space Show team with our two guests discussed a new space solar power technology that uses existing solar panels to collect energy beamed via infrared/near-infrared radiation. David expressed skepticism about the logistics and regulatory challenges, particularly regarding the potential to bypass utility companies like PG&E. The conversation then shifted to introducing both Marc Berte a nuclear engineer from MIT who is now involved with the space show, along with Dr. Paul Jaffe. Marc and Paul discussed space solar power and Marc’s company’s work on building space energy for delivery to Earth.

Marc presented the Overview Energy innovative approach to space solar energy, focusing on wide-beam near-infrared energy transmission from geosynchronous orbit to existing large-scale utility solar projects. He explained that the system requires no modifications to existing solar panels, as it uses near-infrared light matched to the bandgap of common PV materials, achieving up to 60% efficiency compared to 20% with sunlight. Marc addressed regulatory concerns by highlighting that the system operates within Class 1 laser safety regulations worldwide, making it passively safe and compliant with FAA, OSHA, and FDA standards. David inquired about the feasibility of weaponizing the beam, to which Marc responded that it is physically impossible due to the spatially incoherent nature of the laser light used.

The Wisdom Team discussed space solar power systems, with Marc explaining that cloud cover only slightly affects beam availability due to site diversity across different geographical locations. Paul shared his experience at NRL researching various power beaming methods, including microwave and optical systems, before transitioning to commercial projects. The discussion clarified that the satellite system uses geosynchronous orbit (GEO) rather than geostationary orbit (GSO), with each satellite having a 200-meter array capable of delivering about a megawatt of power. Marc noted that while the system is not designed for small, mobile military applications, it could potentially support large military installations like Anderson Air Force Base on Guam.

The discussion focused on the economic and technical considerations of space solar energy, particularly the challenges of small-scale expeditionary power systems. Marc explained that while small, logistically constrained units may not be ideal customers due to concerns about being laser-designated from space, larger bases and power distribution systems are more promising markets. The conversation also covered power density considerations, with Paul and Marc emphasizing that moving vehicles require higher power density than stationary applications, and that Overview’s approach of usi
